Cathedral of Saint Francis de Sales, Gothic Revival cathedral in Baker City, Oregon.

The Cathedral of Saint Francis de Sales is a stone Gothic Revival structure in Baker City's downtown with pointed arches and large stained glass windows throughout. The building features characteristic vertical lines and intricate window designs that define its appearance.

Catholic services in Baker City began in October 1862 in a building the church purchased; a frame church was built on this site in 1871. The Diocese of Baker City was created in 1903 and the church was elevated to cathedral status. The present cathedral was built from 1906 to 1908, with the rectory finished in 1907.

The cathedral is the seat of the Diocese of Baker, which covers all of eastern Oregon and was created in 1903, when St. Francis de Sales Church was raised to cathedral status. The parish traces its origins to Catholic services held in Baker City in October 1862, and a frame church built on this site in 1871. The building also serves as a parish church.

The cathedral stands in Baker City's downtown historic district, with the rectory beside it and the former chancery attached to the north side, covering the lower apse. The main facade with its double entryway and rose window faces the street between two equal towers. Visitors should check opening times before planning a visit and observe posted guidelines during worship services.

The cathedral and its rectory were listed as contributing properties in the Baker Historic District on the National Register of Historic Places in 1978. The rectory, also built of volcanic tuff, was completed in 1907, a year before the cathedral. A diocesan chancery added in the 1960s covers the lower part of the apse.
